Abstract
The invention which provides a lithium metal primary cell negative flake relates to a cell structure, and especially relates to a lithium metal primary cell structure. The negative cell plate comprises a flaky body, a metal strip and a cathode tab, and is prepared according to steps of placing the metal strip on the flaky body, compacting them together, and stitch-inlaying the cathode tab with them to prepare an entirety, wherein the flaky body is a lithium metal foil or a lithium-aluminum alloy foil; the metal strip is a metal mesh or a metal foil, and the material of the metal strip is any one of a copper mesh, a copper foil, an aluminum foil, a nickel mesh, a nickel foil, a steel mesh and a steel foil; and the cathode tab is a pure nickel strip attached with a hot melt adhesive. The negative flake has the advantages of reduction of the internal resistance of the cell, improvement of the utilization rate of the cathode, good conductivity and safety, and high and stable cell discharge plateau, and can effectively avoid the generation of dendritic crystals and lithium death, and the generation of short-circuit and the like.
Description
Technical field:
The present invention relates to battery structure, especially lithium metal primary cell structure.
Background technology:
Existing lithium primary battery metallic lithium foil negative plate on the market, utilance is not high; With the lithium metal primary cell of metal lithium bands as negative plate, negative pole and collector contact resistance are big, and discharge performance is unstable, can not satisfy the cell discharge performance requirement well; Because electric conductivity is not ideal enough, the phenomenon that produces dendrite and dead lithium is prone to poor safety performance takes place.
Summary of the invention:
The objective of the invention is to: the lithium metal primary cell negative plate that a kind of high usage, satisfactory electrical conductivity are provided.
It comprises flake main body, strip metal and negative lug; It is compressed together with it at first on flake main body, to place strip metal, negative lug and its pressing is inlayed process an integral body again.
Described flake main body is metallic lithium foil or lithium-aluminium alloy paper tinsel.
Described strip metal is wire netting or metal forming; Its material is any of copper mesh, Copper Foil, aluminium net, aluminium foil, nickel screen, nickel foil, steel mesh, steel foil.
Described negative lug is to attach PUR on the pure nickel nickel bar.
The present invention has reduced the internal resistance of battery, has improved the utilance of negative pole, and conductivity and safety can be good, and the battery discharge platform is high and stablize; Can effectively avoid producing dendrite and dead lithium, situation such as effectively avoid being short-circuited takes place.
